A system and method for treating organically polluted wastewater in environmental emergency accidents

Abstract

The invention relates to an organic pollution wastewater treatment system in environmental emergent accidents, which comprises a sealing box, an anode and a microporous aeration device, wherein a battery and a gas pump are arranged in the sealing box; the gas pump is connected with the microporous aeration device through an aeration pipe; the side wall of the microporous aeration device is a cathode; the cathode is provided with micropores; the sealing box is connected with a pole plate rack supporting plate; a pole plate rack left side plate and a pole plate rack right side plate are arranged below the pole plate rack supporting plate; the inner sides of the pole plate rack left side plate and pole plate rack right side plate are each provided with a plurality of clamping grooves; the clamping grooves in the pole plate rack left side plate are corresponding to the clamping grooves in the pole plate rack right side plate one by one; the anode and microporous aeration device are respectively provided with clamping pieces matched with the clamping grooves; and the anode is an iron anode. The invention also relates to an organic pollution wastewater treatment method in environmental emergent accidents on the basis of the system, which comprises the following steps: calculating treatment capacity of a single electrode, calculating the number of required electrodes, and treating the wastewater. The method can quickly treat organic wastewater generated by leakage in unexpected environmental accidents and treat organic wastewater which can not conveniently enter the sewage treatment plant (station).

Description

technical field [0001] The invention relates to the field of organic sewage treatment, in particular to a system and method for treating organic polluted wastewater in environmental emergency accidents. Background technique [0002] With the development of the chemical industry, a large number of organic compounds are circulated and transported through vehicles and pipelines. Leakage accidents occur during the process of circulation and transport, or organic matter is polluted to surface water due to illegal discharge, agricultural pollution, etc., polluted The remote location of the water body is difficult to enter the sewage treatment plant (station) for treatment, public transportation (aircraft, car, ship), and the treatment of toilet wastewater that cannot enter the urban pipe network. Contaminated organic wastewater accumulates in ponds and near water banks, which greatly affects the quality of water environment, changes the function of water bodies, affects the safety...

AI Technical Summary

Problems solved by technology

Polluted organic wastewater accumulates in ponds and near water banks, which greatly affects the quality of water environment, changes the function of water bodies, affects the safety of drinking water for residents, and causes huge losses to agriculture, industry, and aquaculture.

In recent years, the rural water environment has been polluted, and the pollution near the waterfront is particularly prominent. This part of the water body cannot enter the sewage treatment plant (station) for treatment, which has a negative impact on the lives of residents.

Traditional organic wastewater treatment plants (stations) use a combination of physicochemical and biological oxidation methods to remove organic matter, requiring fixed, large-volume pools, ditches and other structures, as well as lifting pumps, fans, mixers and other equipment. Chemicals such as flocculants occupy a large area, cannot be moved, have a large one-time investment, and the biochemical system takes a long time to cultivate, so emergency treatment cannot be realized

[0003] For the treatment of leaked organic wastewater in sudden environmental accidents, remote water bodies polluted by organic matter, and coastal polluted waters, the existing fixed equipment in organic wastewater treatment plants is obviously unable to deal with them.
